Today i modded a v4 (not the first, did already over 60 mods) with infinity green dot. Instal ok, booted fine but when I try to upgrade it to 1.68 or 1.75 it wont read the disc. Boots cd's and Dvd fine but not the upgrade disc. Tried to hold reset for 3 sec , red screen . Hold reset for 2 sec it says playstation disc, so i pushed X but comes to the same screen.
Anyone any idea ? By the way PS2 is working fine , just wanted to know what is causing the problem.
